Dear all,

Hannes Tschofenig and myself have submitted an ID for using DTLS 1.3 over SCTP:
https://www.ietf.org/archive/id/draft-tuexen-tsvwg-rfc6083-bis-02.html

This is an alternative to
https://www.ietf.org/archive/id/draft-ietf-tsvwg-dtls-over-sctp-bis-06.html

Our document is based on RFC 6083. The major differences are:
* Use DTLS 1.3 instead of DTLS 1.0
* Use key updates instead of renegotiation. This limits the number of
  rekeyings to 2^64, but that should not limit in real world scenarios.
* Bump the maximum user message size to 64KB by using RFC 8449.

Any comments welcome.

Best regards
Michael
